They have a 50% chance of doing so per hour if left in a box with a flask of poison, a Geiger counter, and a single atom of a radioactive isotope with a half-life of an hour. Or maybe that's dying.
It's not about probability of it happening, it is that it will simultaneously happen and not happen until observed to be one or the other.
Assuming you're interested in the Copenhagen interpretation of quantum physics. Under that interpretation, the cat would have 50% created an artifact and 50% not created one. On the other hand, in the multiple-universes theory, the universe splits into two, one where the artifact was created and one where it was not. For various reasons, including time travel issues, I prefer the latter.

Look, Schrodinger was a closed-minded fool. Superposition of states does happen in the quantum level, and yes, it doesn't work that way when you bring it into the realm of classical mechanics, but there's a bridge we have to cross. He was just being unreasonable. Too bad we observe him to be dead.
Isn't the whole idea with the cat to show that if you accept that for particles superposition of states exists, then it must exist for classical objects also? As it is basically about a thought-experiment where you are giving a cat the wave function of a particle.
It was Schrödinger's attempt at a reductio ad absurdum, but he failed to consider that sometimes what seems absurd to a brilliant physicist is true regardless.
If it was
reduction ad absurdum, what SHOULD happen when you lock the cat in the box? Why should the laws of physics turn off when we lock cats in boxes?
